clamped upon the pipe 17, and after extending forwardly a sho-rt distance beyond the bar 7, the bars 25 turn inwardly and are secured to the rear end of the tongue 26. A transverse bar 27 is centrally mounted beneath the rear end of the tongue and has its extremity connected by brace rods 28 with the members 20. From the rear extremities ofthe beams 21 a pair ofbalance bars 29 Vextend upwardly being provided with. grips 30 near their upper ends. The upper ex tremities ofv said bars have pivotal connection through rods 3l with the pipe 17. A pair of coiled springs 32 establish a connection between the upper portions of the rods 3l and the cross bar 27. The parts 29, 30, 3l and 32 are not claimed as a part of this invention since they are already in common use, and are shown merely to present a complete machine.

Upon the tongue adjacent to the rear of the end thereof is slidably mounted a weight 38, guided in its motion by a pair of plates 84. This weight which is intended to act as a counter balance to the weight of the driver, is adapted to be adjusted by means of a lever 35 to .which the weight is pivotally attached by a rod 36.

Upon the forward extremities of the bars 6 are mounted a pair of angular members 37, each having one of its parts slotted as indicated at 38. rlhe membersv 37 are mounted on the bars 6, suitable fastenings being passed through the slots 38 andlsecured in the bars. rJhe angular portions of the members 37 are directed inward longitudinally of the bar 7. By adjusting the members 37 toward and from the bar 7 the amplitude of the arc in which the bars 6 swing, may be regulated, and by adjusting the members so that they contact with bar 7, the bars 6 may be fastened -in fixed relation to said bar 7. @wing to the connection established between the bars 6 and the beams 2l, any motion to which one of the members is subjected will be communicated to the other. y

VThe important feature of the` invention lies in the fact that the cultivator beams may be shifted at an angle with the direction of travel so that the plows may be made to avoid any small obstacle such as a stone or a` root without requiring the driver to deviate the machine from its path. The driver willaccomplish each adjustment by'pr'essing-with his vfoot against one of the beams and at the same time manipulating the upright bars 29. Y l

rlhe invention is presented as including` all suchY changes and-moditlcations as come within the scope ofthe following claims. ,l/Vhat I claim is l. A cultivator,comprisinga pair of trans` l porting wheels, a pair of standards upon the lowerextremities of whichthe tremsport;V

wardly from the lowerextremities ofk the ,i l'

arch bar, and a pair of adjustable rightangled brackets mounted on said parallel bars and bearing against said cross bar. v

2. A cultivator,comprisinga pair or transporting wheels, a pairfofstandards upon the lower extremities of which the transporting wheels are rotatably. mounted,a pair of parallel bars havingtheir rear extremities pivotally' mounted upon the upperends Y of said standards, a cross bar pivotally connecting the forward extremities of said bars, an` arch. bar; attached to said cross bar, a pair of cultivator beams extendingV rearwardly from the lower extremities of the Y arch bar, and a pair of adjustably slotted brackets mounted on said parallel bars and arranged to bear against saidy cross bar.

In testimony whereofl` have signed my name to this specification in the presence of two subscribing witnesses.
